Reinforcement of armored earth work constructions

Abstract

The outer skin of armored earthwork constructions is attached to bands and the traction is transmitted to the ground by friction. The bands are made of a corrosion resistant, high strength weave or netting of reinforced organic, glass or carbon fibres or fibre mixtures and are preferably impregnated with liquid reaction resins such as epoxide, polyurethane or isocyanate resins. It is advantageous to impregnate the bands and then to harden them only after they have been laid.

What we claim is: 
     
       1. A method of reinforcing an armoured earthwork construction comprising the steps of: providing at least one exposed connecting element in the outer skin of at least one building member; impregnating at least one high-strength corrosion-resistant netted or weaved band with liquid reaction resins, which harden after the band has been embedded in the earth; wrapping each band around a connecting element; and embedding the free ends of the band in the earth. 
     
     
       2. The method according to claim 1, wherein the bands are impregnated after wrapping and before being embedded. 
     
     
       3. The method according to claim 1 or claim 2, wherein the reaction resins are epoxide, polyurethane or isocyanate resins. 
     
     
       4. The method according to claim 1, wherein the bands have a warp and a weft and are reinforced principally in the warp direction. 
     
     
       5. The method according to claim 1, wherein the bands comprise synthetic organic fibers. 
     
     
       6. The method according to claim 1, wherein the bands comprise glass fibres, carbon fibres or fibre mixtures thereof. 
     
     
       7. The method according to claim 1, wherein the step of wrapping comprises bending one end portion of each band back on itself to form overlapping portions and clamping the overlapping portions together. 
     
     
       8. The method according to claim 1, wherein the step of wrapping comprises bending one end portion of each band back on itself to form overlapping portions and wherein the overlapping portions are connected upon the hardening of the resin. 
     
     
       9. The method according to claim 2, wherein the step of wrapping comprises bending one end portion of each band back on itself to form overlapping portions and joining the overlapping portions by thereafter impregnating same with the resin and allowing the resin to harden. 
     
     
       10. The method according to claim 9, wherein the reacting resin is a cold setting epoxide resin comprising dibutylamine as a hardener. 
     
     
       11. An armoured earthwork construction comprising: at least one building member having an outer skin with at least one exposed connecting element therein and at least one high strength, corrosion-resistant, netted or weaved band impregnated with liquid reaction resins which harden after the band is embedded in the earth, each wrapped around the connecting element with the free ends thereof embedded in the earth. 
     
     
       12. The construction according to claim 11, wherein the bands have a warp and a weft and are reinforced principally in the warp direction. 
     
     
       13. The construction according to claim 11, wherein the bands comprise synthetic organic fibers. 
     
     
       14. The construction according to claim 11, wherein the bands comprise glass fibres, carbon fibres or fibre mixtures thereof. 
     
     
       15. The construction according to claim 11, wherein the reaction resins are epoxide, polyurethane or isocyanate resins. 
     
     
       16. The construction according to claim 11, wherein the band is wrapped around the connecting element and back on itself to form overlapping portions and further comprising a clamp for connecting the overlapping portions together. 
     
     
       17. The construction according to claim 11, wherein the band is wrapped around the connecting element and back on itself to form overlapping portions and wherein the overlapping portions are connected upon the hardening of the resin. 
     
     
       18. The construction according to claim 17, wherein the reacting resin is a cold setting epoxide resin comprising dibutylamine as a hardener.
